Complete Over 4kWh list
Every power station over 4,000 Wh we track
The complete tracked list of mega-capacity systems for long-duration backup and the heaviest portable-power loads — every model in the band, not a shortlist.
01
Lineup at a glance
All 5 tracked stations with a sourced rated capacity above 4,201 Wh, listed in full — this page never trims the band to a shortlist. For the scored shortlist, the Best for home backup ranking applies the BatteryRank composite to this same pool and publishes only the top scorers.

Use the model dossier for complete specifications. When enough history exists, the card links to a dedicated price-history page rather than forcing price intent onto this comparison page.

Frequently asked
- How is this different from the Best for home backup ranking?
- This page is the inventory: all 5 tracked models inside the band, in catalog order, so nothing is hidden from you. The ranking is the shortlist — it applies the BatteryRank composite and publishes only the top scorers. Come here to see what exists; go there to see what scores best. Best for home backup →
- Is every over 4kwh model on this page?
- Every model BatteryRank tracks with a sourced rated-capacity reading inside the band appears here — currently 5. A model with no sourced capacity figure is withheld rather than estimated into a band it may not belong in.
- How are models included in this size class?
- A station is included by its sourced rated watt-hours and the published class boundaries shown on this page. Models outside the band belong to an adjacent size page.
- Is the highest-capacity model here automatically the best?
- No. More capacity usually brings different weight, output, charging, expansion, and price tradeoffs. Capacity decides which page a model appears on; it decides nothing else.
- How much usable AC energy should I expect?
- Usable AC energy is lower than nameplate capacity because of conversion losses. Model cards show a measured range when credible independent data exists; otherwise they show a transparent estimate.
- Can this size run a refrigerator or CPAP?
- Runtime depends on the device draw, duty cycle, settings, and conversion path. Use the device-specific tools rather than a generic size-page promise. Estimate your load →
- Why is price not part of the score?
- Price changes daily; a station’s hardware does not. Keeping price out of the score means a discount can never buy a better rank, and the score you read today means the same thing next week.
- Where are exact model matchups?
- Model-vs-model pages own exact head-to-head decisions. This page owns the broader capacity-class search. Compare exact models →
- Are all specifications verified?
- No. Manufacturer claims are labeled claimed; credible independent or regulatory evidence is labeled verified. A missing reading stays N/A.
